Disentanglement by Dissipative Open System Dynamics | | P.J. Dodd
; | | Date: |
11 Dec 2003 | | Subject: | quant-ph | | Abstract: | This paper investigates disentanglement as a result of evolution according to a class of master equations which include dissipation and interparticle interactions. Generalizing an earlier result of Diósi, the time taken for complete disentanglement is calculated (i.e. for disentanglement from any other system). The dynamics of two harmonically coupled oscillators is solved in order to study the competing effects of environmental noise and interparticle coupling on disentanglement. An argument based on separability conditions for gaussian states is used to arrive at a set of conditions on the couplings sufficient for all initial states to disentangle for good after a finite time. | | Source: | arXiv, quant-ph/0312099 | | Other source: | [GID 160669] quant-ph/0312099 | | Services: | Forum | Review | PDF | Favorites | |
